New UMF 250 Quick-Acting SMD Fuse

Schurter expanded its line of surface-mount fuses with the introduction of the Universal Modular Fuse, UMF 250. Its quick-acting characteristic according to IEC 60127-4 complements the successful UMT series, in providing overcurrent and short circuit protection for electronic systems in primary and secondary circuits.

Current ratings up to 10 A at 250 VAC/125 VDC, the UMF 250 has a breaking capacity of up to 200 A at rated voltage.  The UMF 250 provides maximum circuit protection while its extremely compact size saves PCB space over larger cartridge style fuses and facilitates assembly with pick and place mounting. The UMF 250 is ideal in applications such as power supplies, medical equipment, and devices for home and industrial use. The UMF 250 is RoHS compliant and carries cURus and VDE approvals.

A Dash of Maxwell’s: A Maxwell’s Equations Primer – Part Two

Maxwell’s Equations are eloquently simple yet excruciatingly complex. Their first statement by James Clerk Maxwell in 1864 heralded the beginning of the age of radio and, one could argue, the age of modern electronics.

Pricing for the UMF 250 starts at about $0.73 each for 100 pieces. The fuse is supplied in loose packs of 100 pieces or a 2000 piece blister tape reel for automated assembly. See detailed specifications at For sales and product information, contact Cora Umlauf at 800 848-2600 or
